    Would be nice if we change the language of a particular application! I have applications that are in different languages. – Aero Windwalker Jan 31 '15 at 21:36

Also there are tools to change locale for a single application:

  1. Locale Emulator.

  2. Ntleas.

  3. Micosoft AppLocale Wizard, which is not updated for a decade, and even not hosted for a few years so no one can find a copy of it, but it seems still some people utilize it through compatibility troubleshooter, or through this more complex approach.
